Rapid Access Addiction Medicine Clinics for People With Problematic Opioid Use.

Area of Science:

• Addiction Medicine
• Public Health
• Health Services Research

Background:

• Problematic opioid use (POU) requires innovative care models.
• Rapid Access Addiction Medicine (RAAM) clinics offer low-barrier, timely treatment.
• The impact of RAAM on healthcare utilization for POU is not fully understood.

Purpose of the Study:

• To evaluate the association between RAAM clinic care and healthcare outcomes.
• To assess the impact of RAAM on emergency department (ED) visits, hospitalizations, and mortality in individuals with POU.

Main Methods:

• Retrospective cohort study using health administrative data from Ontario, Canada.
• Propensity score matching to compare individuals receiving RAAM care with a matched control group.
• Analysis of composite outcomes (ED visits, hospitalizations, mortality) at 30 and 90 days post-initiation.

Main Results:

• RAAM care was associated with a significant reduction in the composite outcome of ED visits, hospitalizations, or mortality within 30 days (OR, 0.68).
• Opioid-related ED visits and hospitalizations were also significantly reduced in the RAAM group (OR, 0.47).
• Individual outcomes favored the RAAM model across 30-day and 90-day follow-up periods.

Conclusions:

• RAAM clinics are associated with decreased healthcare utilization and mortality for individuals with POU.
• Findings support the expansion of RAAM models to improve care for this population.
• Evidence suggests RAAM is an effective approach for managing problematic opioid use.
